Wiring Guide

7 of 12 © 2008 W 335 - 12/08
This section explains how to wire individual devices to
the Zone Manager 335. For step by step wiring refer to the
terminal number on the right of the page.
•
• Before wiring ensure all power is turned off and take all
necessary precautions.
•
• Install the supplied wiring compartment barriers by
sliding them into the grooves provided to isolate the low
and high voltage wiring.
Terminals 1 and 2 provide a tN4 connection for tN4 devices
on the tN4 bus. Connect terminals 1 (tN4) and 2 (C) to the
corresponding terminals on the tN4 devices that are to be
connected.
Polarity is important.
Ensure that terminal 1 (tN4) is connected to the tN4 terminal
on the tN4 device and that terminal 2 (C) is connect to the
C terminal on the tN4 device.

• Connect the tN4 terminal on the Zone Manager to the
tN4 terminal on the thermostat.
•
• Connect the C terminal on the Zone Manager to the C
terminal on the thermostat.
•
• Connect the R terminal on the Zone Manager to the R
terminal on the thermostat.
•
• Connect the W terminal on the Zone Manager to the W
or W1 terminal on the thermostat (or W2 in the case of
second stage heat).
